Description
本発明は、炭素質熱源を備えた非燃焼型喫煙物品に関する。
The present invention relates to a non-combustion smoking article provided with a carbonaceous heat source.
近年、シガレットに代わり、タバコを燃焼させることなく、香味を味わう非燃焼型喫煙物品が開発されている。非燃焼型喫煙物品は、先端に取付けた発熱部材である熱源部と、適当な基材に香味成分を保持させた香味発生材を含む香味発生部を備える。熱源部としては主に炭素質熱源が用いられている。
In recent years, instead of cigarettes, non-combustion smoking articles have been developed that taste flavor without burning tobacco. The non-combustion type smoking article includes a heat source part which is a heat generating member attached to the tip, and a flavor generating part including a flavor generating material in which a flavor component is held on a suitable base material. A carbonaceous heat source is mainly used as the heat source.
これまでの炭素質熱源には、エアロゾル発生部が加熱される際の空気流路として機能し、初期の燃焼特性を発揮させるために設けられる複数の貫通孔が軸方向に設けられている(米国特許第4,881,556号明細書、米国特許第4,967,774号明細書、米国特許第4,989,619号明細書、米国特許第4,991,606号明細書、米国特許第5,067,499号明細書)。また、熱源部分を特殊な構造に形成している例もある(米国特許第5,183,062号明細書)。これらの多くの非燃焼型喫煙物品用の炭素質熱源は巻紙や断熱材により巻かれている。さらに、従来の炭素質熱源は、60重量%、好ましくは80重量%を超えるカーボンを含むことが好都合であるとされている。
Conventional carbonaceous heat sources are provided with a plurality of through-holes provided in the axial direction to function as an air flow path when the aerosol generating unit is heated and to exhibit initial combustion characteristics (US) Patent No. 4,881,556, US Pat. No. 4,967,774, US Pat. No. 4,989,619, US Pat. No. 4,991,606, US Pat. No. 5,067,499). There is also an example in which the heat source part is formed in a special structure (US Pat. No. 5,183,062). The carbonaceous heat source for many of these non-combustible smoking articles is wrapped with wrapping paper or insulation. Furthermore, it is expedient for conventional carbonaceous heat sources to contain more than 60% by weight, preferably more than 80% by weight of carbon.
従来の炭素質熱源は、確かに熱を効率よくエアロゾル発生部に伝えるという点において改善されている。しかし、熱源組成物の押し出し成形品からなる加熱源は、複数設けられた空気の流路以外は中実の物品であり、通常のシガレットに比べて、着火させることが困難である。また、用いるカーボン量が多いことで、燃焼中に炭素質熱源が収縮し、喫煙物品から脱落するおそれがある。さらに、熱を効率よくエアロゾル発生部に伝え、かつ脱落を防止するために、熱源部を断熱材等で覆うことが殆どである。
The conventional carbonaceous heat source is certainly improved in that it efficiently transfers heat to the aerosol generating part. However, the heat source composed of an extrusion-molded product of the heat source composition is a solid article except for a plurality of air flow paths, and is difficult to ignite as compared with a normal cigarette. In addition, the large amount of carbon used may cause the carbonaceous heat source to shrink during combustion and fall off the smoking article. Furthermore, in order to efficiently transfer heat to the aerosol generating part and to prevent falling off, the heat source part is mostly covered with a heat insulating material or the like.
従って、本発明は、着火性が向上し、喫煙中に脱落しにくく、その周囲に断熱材等の包装材を必要としない炭素質熱源を有する非燃焼型喫煙物品を提供することを目的とする。
Accordingly, an object of the present invention is to provide a non-combustion type smoking article having a carbonaceous heat source that has improved ignitability, is less likely to fall off during smoking, and does not require a packaging material such as a heat insulating material. .

炭素質熱源の空隙率は50%以上とすることができる。ここで、「炭素質熱源の空隙率」とは、熱源の横断面において、隔壁により区画されることにより生じる、熱源の断面積あたりの空間の割合を意味する。空隙率が50%未満であると、着火時の着火性が大幅には向上しない傾向にある。空隙率の上限は、熱源組成物を押出成形する際の金型の設計により制限される。炭素質熱源の空隙率は、好ましくは50%~78%、より好ましくは60~78%である。このように大きな空隙率をもつ炭素質熱源を備えた本発明の非燃焼型喫煙物品は着火性が向上する。

Here, the “porosity of the carbonaceous heat source” means the ratio of the space per cross-sectional area of the heat source, which is generated by being partitioned by the partition wall in the cross section of the heat source. When the porosity is less than 50%, the ignitability at the time of ignition tends not to be significantly improved. The upper limit of the porosity is limited by the design of the mold when extruding the heat source composition.

For the carbonaceous heat source, it is possible to coat a desired substance on a part or all of the axial surface of the air flow path. In particular, it is possible to make the carbonaceous heat source substantially air impermeable by coating a layer of particles. The coating material desirably has low thermal conductivity, is thermally stable, and is nonflammable at the temperature at which the carbonaceous heat source burns. Suitable coating materials include clays and metal oxides such as iron oxide, alumina, titania, silica, silica alumina, zirconia, ceria, zeolite, zirconium phosphate, other ceramics and combinations thereof. These coating materials preferably contain clay and iron oxide. These coating materials can also contain a catalyst having a function of promoting an oxidation reaction from carbon monoxide to carbon dioxide. Examples of these catalysts include platinum, palladium, other transition metals, and oxides thereof.
空気流路の軸方向の表面の一部もしくは全てに所望の物質をコーティングするために、米国特許第5,040,551号明細書に記載されるような種々の方法を用いることができる。例えば、コーティング物質の溶液あるいは懸濁液を散布するか(spray)、濡らすか(wet)、塗る(paint)こともできる。あるいは、コーティング物質からなるライナーを空気流路の軸方向の表面の一部もしくは全てに挿入してもよい。例えば、実質的に空気不透過性の中空管を各々の空気流路の軸方向に挿入してもよい。
Various methods as described in US Pat. No. 5,040,551 can be used to coat a desired substance on part or all of the axial surface of the air flow path. For example, a coating solution or suspension can be sprayed, wetted or painted. Alternatively, a liner made of a coating substance may be inserted into part or all of the axial surface of the air flow path. For example, a substantially air impermeable hollow tube may be inserted in the axial direction of each air flow path.
本発明の非燃焼型喫煙物品に用いられる炭素質熱源は、横断面が格子をなす隔壁の形態を保ったまま燃焼する。これは上記の通り熱源組成物のカーボン量が従来よりも抑えられているためと考えられる。従って、以下の通り断熱材等により熱源が覆われていなくても、喫煙時に喫煙物品から熱源が脱落することを防ぐことができる。
The carbonaceous heat source used in the non-combustion type smoking article of the present invention burns while maintaining the shape of the partition wall whose cross section forms a lattice. This is presumably because the carbon content of the heat source composition is suppressed as compared with the conventional case. Therefore, even if the heat source is not covered with a heat insulating material or the like as described below, it is possible to prevent the heat source from dropping from the smoking article during smoking.
上記した炭素質熱源は、所望の格子に対応する金型を用いて、押し出し成形等の成形手段により成形することができる。本発明において用いられる炭素質熱源は、通常の非燃焼型喫煙物品のようにその周囲に断熱材や巻紙等を設ける必要がなく、むき出しのままで十分に燃焼し、また脱落しにくい。このように炭素質熱源の周囲に断熱材等を設ける工程を省くことができ、コスト的にも非常に有利である。
The above-mentioned carbonaceous heat source can be molded by a molding means such as extrusion molding using a mold corresponding to a desired lattice. The carbonaceous heat source used in the present invention does not need to be provided with a heat insulating material, a wrapping paper, or the like around it like a normal non-combustion type smoking article, and is sufficiently burned and not easily dropped off. Thus, the step of providing a heat insulating material or the like around the carbonaceous heat source can be omitted, which is very advantageous in terms of cost.
本発明の非燃焼型喫煙物品には、たとえば、炭素質熱源と物理的に分離した形態で、エアロゾル発生部を設けることができる。エアロゾル発生部に含まれるエアロゾル発生物質としては、たとえば、グリセリン、プロピレングリコール、トリエチレングリコール、テトラエチレングリコール等の多価アルコール、ステアリン酸メチル、ドデカン二酸ジメチル、テトラデカン二酸ジメチル等のカルボン酸脂肪族エステルを用いることができる。エアロゾル発生物質は、通常、適当な担体に担持される。担体としては、紙、活性炭等の多孔質材料を用いることができる。エアロゾル発生物質を多孔質材料に吸収ないし吸着させてエアロゾル発生材を調整する。あるいは、担体として、特許第3118462号明細書に記載されている、カードラン等のグルカンゲルを用いることができる。すなわち、熱不可逆凝固性グルカンの水中分散液にエアロゾル発生物質を添加し、たとえばステンレス鋼製ベルト上に薄膜シート状にキャスティングした後、加熱乾燥してグルカンをゲル化させる。このエアロゾル発生物質を保持したグルカンゲルは、裁刻しまたは粉末化してエアロゾル発生材として用いることができる。
In the non-combustion type smoking article of the present invention, for example, an aerosol generating part can be provided in a form physically separated from a carbonaceous heat source. Examples of the aerosol generating substance contained in the aerosol generating part include polyhydric alcohols such as glycerin, propylene glycol, triethylene glycol, and tetraethylene glycol, and carboxylic acid fats such as methyl stearate, dimethyl dodecanedioate, and dimethyl tetradecanedioate. Group esters can be used. The aerosol generating substance is usually carried on a suitable carrier. As the carrier, a porous material such as paper or activated carbon can be used. The aerosol generating material is adjusted by absorbing or adsorbing the aerosol generating material on the porous material. Alternatively, glucan gel such as curdlan described in Japanese Patent No. 3118462 can be used as the carrier. That is, an aerosol generating substance is added to an aqueous dispersion of heat irreversibly solidified glucan, and cast into a thin film sheet on a stainless steel belt, for example, and then dried by heating to gel the glucan. The glucan gel holding the aerosol generating substance can be cut or powdered and used as an aerosol generating material.
エアロゾル発生物質を担体に保持させたエアロゾル発生材を、ガラス繊維を含有する紙シート、セラミック、金属箔で内張りされた紙シート等の不燃性材料で形成された円筒体内に収容してエアロゾル発生部を構成することができる。
An aerosol generating material in which an aerosol generating material having an aerosol generating substance held on a carrier is contained in a cylindrical body formed of a nonflammable material such as a paper sheet containing glass fiber, a ceramic, or a paper sheet lined with a metal foil.

実施例1
炭素質熱源の空隙率、炭素質熱源の流路周長、熱源断面積、および熱源断面積当たりの流路周長と着火性との関係を検討した。 Example 1
The relationship between the porosity of the carbonaceous heat source, the channel circumference of the carbonaceous heat source, the heat source cross-sectional area, and the channel circumference per heat source cross-sectional area and the ignitability were investigated.
炭素質熱源の空隙率、炭素質熱源の流路周長、熱源断面積、および熱源断面積当たりの流路周長と着火性との関係を検討した。 Example 1
The relationship between the porosity of the carbonaceous heat source, the channel circumference of the carbonaceous heat source, the heat source cross-sectional area, and the channel circumference per heat source cross-sectional area and the ignitability were investigated.
従来の非燃焼型喫煙物品(日本たばこ産業株式会社製;商品名エアーズ)に使用されている熱源組成物と同一の組成、すなわち59.6重量%のカーボン粒子、12重量%の炭酸カルシウム、8.4重量%のグラファイトおよび10重量%のタバコ細粉を原料として熱源組成物を調製した。この熱源組成物を、種々の金型を用いて隔壁の肉厚および格子の間隔が異なるように成形し、表1に示す端面の形態を有するサンプル1~6の炭素質熱源を作製した。
The same composition as the heat source composition used in a conventional non-combustion smoking article (manufactured by Nippon Tobacco Inc .; trade name Ayers), that is, 59.6% carbon particles, 12% calcium carbonate, 8 A heat source composition was prepared using 4 wt% graphite and 10 wt% tobacco fine powder as raw materials. This heat source composition was molded using various molds so that the wall thickness of the partition walls and the lattice spacing were different, and the carbonaceous heat sources of Samples 1 to 6 having the form of the end faces shown in Table 1 were produced.
次いで、上記エアーズ製品から熱源およびこれを取り巻く断熱材を抜き取り、上記の通り作製したサンプル1~6の炭素質熱源を挿入した。すなわち、熱源以外の喫煙物品の構成はエアーズ製品と同一である。
Next, the heat source and the heat insulating material surrounding it were extracted from the Ayers product, and the carbonaceous heat sources of Samples 1 to 6 prepared as described above were inserted. That is, the configuration of the smoking article other than the heat source is the same as that of the Ayers product.
従来例1
従来例1として、上記した日本たばこ産業株式会社製の商品名エアーズである非燃焼型基喫煙物品を用いた。 Conventional example 1
As Conventional Example 1, a non-combustion-type basic smoking article, which is a trade name Ayers manufactured by Nippon Tobacco Inc., was used.
従来例1として、上記した日本たばこ産業株式会社製の商品名エアーズである非燃焼型基喫煙物品を用いた。 Conventional example 1
As Conventional Example 1, a non-combustion-type basic smoking article, which is a trade name Ayers manufactured by Nippon Tobacco Inc., was used.
着火性試験は次の通り行なった。電気式ライターで3秒間予備加熱後、35ml/2秒で吸煙させた。次に、58秒後に再度吸煙させ(即ち、60秒の喫煙サイクル)、その際に熱源全体が赤熱するかを目視で確認し、赤熱したものを「着火可」、赤熱しなかったものを「着火不可」として判定した。サンプル1~6、従来例1についてそれぞれ10本の喫煙物品を用いて試験を行い、そのうち「着火可」と確認されたものの本数をAとして、「着火率=A÷10×100(%)」より着火率を算出した。
The ignitability test was conducted as follows. After preheating with an electric lighter for 3 seconds, smoke was absorbed at 35 ml / 2 seconds. Next, smoke is absorbed again after 58 seconds (that is, a smoking cycle of 60 seconds). At that time, it is visually confirmed whether the entire heat source is red-hot, the red-hot one is “ignitable”, and the one that is not red-hot is “ It was determined as "Ignition is impossible" Samples 1 to 6 and Conventional Example 1 were tested using 10 smoking articles, and the number of items that were confirmed to be “ignitable” was A, and “ignition rate = A ÷ 10 × 100 (%)” From this, the ignition rate was calculated.
着火率の解析に当たり、炭素質熱源の断面積当たりの流路周長に対する着火率を検討した。その結果を図3に示す。丸印はサンプル1~6の炭素質熱源の着火率を示し、三角印は従来例1の炭素質熱源の着火率を示している。本条件ではサンプル1~2では、従来例1とあまり着火率について差が見られなかったが、サンプル3では着火率が約60%と大きく向上した。つまり、着火性を向上するためには、表1に示す炭素質熱源の各パラメータの設計が重要であることがわかった。また、横断面が格子をなす隔壁により区画された空気流路を有する炭素質熱源を用いることにより、従来の開孔パターンを有する炭素質熱源に比べ、空隙率および流路周長を大幅に増加することが可能となり、結果として着火性が向上することが確認できた。
In the analysis of the ignition rate, the ignition rate with respect to the flow path circumference per cross-sectional area of the carbonaceous heat source was examined. The result is shown in FIG. Circles indicate the ignition rates of the carbonaceous heat sources of Samples 1 to 6, and triangles indicate the ignition rates of the carbonaceous heat source of Conventional Example 1. Under these conditions, the samples 1 and 2 did not show much difference in the ignition rate from the conventional example 1, but in the sample 3, the ignition rate was greatly improved to about 60%. That is, in order to improve the ignitability, it was found that the design of each parameter of the carbonaceous heat source shown in Table 1 is important. In addition, by using a carbonaceous heat source with an air flow path partitioned by partition walls whose cross section forms a lattice, the porosity and flow path circumference are greatly increased compared to a carbonaceous heat source with a conventional aperture pattern. As a result, it was confirmed that the ignitability was improved.
実施例2
上記表1に示す各パラメータのうち、格子数(流路周長)の影響のみを確認するため、空隙率と熱源断面積を一定にし、流路周長を変化させて試験を行なった。 Example 2
In order to confirm only the influence of the number of lattices (flow path circumference) among the parameters shown in Table 1 above, the test was performed by changing the flow path circumference while keeping the porosity and the heat source cross-sectional area constant.
上記表1に示す各パラメータのうち、格子数(流路周長)の影響のみを確認するため、空隙率と熱源断面積を一定にし、流路周長を変化させて試験を行なった。 Example 2
In order to confirm only the influence of the number of lattices (flow path circumference) among the parameters shown in Table 1 above, the test was performed by changing the flow path circumference while keeping the porosity and the heat source cross-sectional area constant.
サンプル1~6と同様の熱源組成物を調製し、各種金型を用いて表2に示すサンプル7~11の炭素質熱源を作製した。即ち、熱源断面積および空隙率が一定になるように、格子の肉厚と間隔の組み合わせを変更し、流路周長を変化させた。
Heat source compositions similar to those of Samples 1 to 6 were prepared, and carbonaceous heat sources of Samples 7 to 11 shown in Table 2 were prepared using various molds. That is, the perimeter of the flow path was changed by changing the combination of the wall thickness and the interval of the lattice so that the heat source cross-sectional area and the porosity were constant.
次に、エアーズ製品から熱源およびその周囲の断熱材を抜き取り、作製したサンプル7~11の熱源を挿入した。即ち、熱源以外の非燃焼型喫煙物品の構成はエアーズ製品と同一である。
Next, the heat source and the surrounding heat insulating material were extracted from the Ayers product, and the heat sources of the produced samples 7 to 11 were inserted. That is, the configuration of the non-combustion smoking article other than the heat source is the same as that of the Ayers product.
本例では、着火性試験として、電気式ライターで2秒間予備加熱後、35ml/2秒で吸煙させた。実施例2の炭素質熱源は着火しやすく、実施例1の条件下では差が出にくいため、予備加熱時間を3秒間から2秒間に短縮して着火率に差が出るようにした。
In this example, as an ignitability test, smoke was absorbed at 35 ml / 2 seconds after preheating with an electric lighter for 2 seconds. The carbonaceous heat source of Example 2 is easy to ignite, and it is difficult to make a difference under the conditions of Example 1. Therefore, the preheating time was shortened from 3 seconds to 2 seconds so that the ignition rates differed.
図4に炭素質熱源の断面積当たりの流路周長に対する着火率の関係を示す。ここで、予備加熱時間として2秒間および3秒間を用いた場合をそれぞれ示す。図4から3秒間予備加熱した場合の着火率は60%以上と十分に高いことがわかる。また、予備加熱時間を2秒間に短縮したものについては、サンプル1~6と同様に、「熱源断面積当たりの流路周長」の増加により着火率が向上する関係が確認された。これと共に、熱源断面積および空隙率がほぼ一定となる条件下において、隔壁の厚さを極力薄くし、格子の間隔を狭くして格子数を増やすことにより、流路周長を増加させることが、着火性の向上に対して有効であることが認められた。
Fig. 4 shows the relationship of the ignition rate to the flow path circumference per cross-sectional area of the carbonaceous heat source. Here, the case where 2 seconds and 3 seconds are used as preheating time is shown, respectively. It can be seen from FIG. 4 that the ignition rate when preheated for 3 seconds is sufficiently high at 60% or more. In addition, in the case where the preheating time was shortened to 2 seconds, the relationship in which the ignition rate was improved by increasing the “circumference of the flow path per heat source cross-sectional area” was confirmed as in Samples 1 to 6. At the same time, under the condition that the cross section of the heat source and the porosity are almost constant, the circumference of the flow path can be increased by reducing the thickness of the partition walls as much as possible, narrowing the lattice spacing and increasing the number of lattices. It was confirmed that it was effective for improving the ignitability.
